Guys,

I have tested my MB 92 car, last friday in my dealers shop, and it gave me the below results, they told me that I have a problem and they would like to fix it, when I asked them what is it, they replied, "Don't worry we will fix it". and they gave me a paper ;from a testing device called SUN; that printed on it the below things...

For me I don't know what is it, so can any MB professional body analyze the below readings for my engine and tell me what is the problem.
